AP Precalculus Sections covered…

2.5 Exponential Function Context and Data Modeling
2.6 Competing Function Model Validation
2.7 Composition of Functions
2.8 Inverse Functions

In this video, I thoroughly describe and reteach the main components of the sections listed above found in the official College Board AP Precalculus course description found at https://apcentral.collegeboard.org/me.... Afterwords, I provide multiple examples and give descriptive solutions to AP Precalculus-style problems. Topics in this video include…

2.5 Exponential Function Context and Data Modeling:
This topic explores exponential functions and how they can be used to model real-world situations, such as population growth, financial investments, or decay processes. Students learn to analyze and apply exponential functions to represent data and make predictions.

2.6 Competing Function Model Validation:
Competing function model validation involves comparing and evaluating different mathematical models to determine which one best fits a given set of data. This helps in selecting the most appropriate function to describe a specific phenomenon.

2.7 Composition of Functions:
Composition of functions is the process of combining two or more functions to create a new function. Students learn to perform these operations, which are fundamental for solving complex mathematical problems and analyzing relationships between variables.

2.8 Inverse Functions:
Inverse functions are pairs of functions that "undo" each other. In this topic, students study how to find and work with inverse functions, which can be useful for solving equations and understanding relationships between variables in reverse order.

I have many informative videos for Pre-Algebra, Algebra 1, Algebra 2, Geometry, Pre-Calculus, and Calculus. Please check it out:    / nickperich
